置换的戴克路径上的面积

The area above the Dyck path of a permutation

Mark Dukes, Astrid Reifegerste

摘要:

本文研究了从置换到Dyck路的映射。一个戴克路径产生的(杨)图,我们给统计排列和统计之间的关系,其相应的图表。分布的大小,这张图进行了讨论,并概括了奇偶校验结果由于西蒙和施密特。我们提出了一个填充的图,它确定的置换唯一。图包含在一个受限制的类的排列被证明是有关的强Bruhat偏序集。

英文摘要:

In this paper we study a mapping from permutations to Dyck paths. A Dyck path gives rise to a (Young) diagram and we give relationships between statistics on permutations and statistics on their corresponding diagrams. The distribution of the size of this diagram is discussed and a generalisation given of a parity result due to Simion and Schmidt. We propose a filling of the diagram which determines the permutation uniquely. Diagram containment on a restricted class of permutations is shown to be related to the strong Bruhat poset.
